What's Eating Gilbert Grape

Life is a terrible thing to sleep through.

What's Eating Gilbert Grape is a 1993 film starring Johnny Depp as the eponymous Gilbert Grape. The story deals with the Grape household and their friends and acquaintances from Endora, Iowa. Picking up a few years after the suicide of Gilbert's father we see its impact on everyone involved.

One of the main difficulties the family is having concerns Arnie Grape (played by Leonardo DiCaprio), who is developmentally disabled which creates a great deal of problems for everyone involved, especially the multiple times he climbs the town water tower and refuses to get down for everyone, except his brother Gilbert.

Gilbert ends up chafing against his role as the new man of the house, along with having to find his way through romantic tensions with a married woman, preparations for a grand party for Arnie's 18th Birthday, his morbidly obese mother's declining health, and worrying about his future career.

Tropes used in What's Eating Gilbert Grape include:

Knight in Sour Armor: Gilbert does everything for his family without complaint, but is secretly resentful about it to his friends.
Make It Look Like an Accident: discussed by Gilbert's friends about Mr. Carver (who also happens to be offering Gilbert a job while his wife tries to get Gilbert to sleep with her) after he drowns to death in a kiddy pool party, argued to be subverted because he had a heart attack that caused him to collapse in such a way that he drowned in a kiddy pool.

My God, What Have I Done?: At the beginning of the movie, Arnie - the mentally challenged young man - kills a grasshopper by beheading it, and then cries to Gilbert about it. Later on in the movie, Gilbert loses his cool - leading him to slap Arnie around, after being so protective of him.
